Abstract

PURPOSE:To uniformize magnetic flux density in a gap between magnetic poles by forming a vertical section of a coil setup to the orbital direction of a charged particle beam as specified, in case of a deflecting magnet at a synchrotron radiation generator or the like. CONSTITUTION:A pair of opposed cryostats 6, having a superconducting coil of a deflecting magnet built in, are set up in a void in a cold core 1, and upper superconducting coils 2a, 2b and lower superconducting coils 2a', 2b' are installed symmetrically with respect to an orbital surface of a charged particle beam 5. In addition, a vertical space h2 of these coils 2a, 2b at the outer circumferential side of an orbit of the beam 5 is made larger than a vertical space h1 of the coils 2a, 2b at the inner circumferential side, while the horizontal width of a return yoke 7b at the outer circumferential side is made larger than that of a return yoke 7a at the inner circumferential side and as for the sectional form, the inner circumferential side and the outer circumferential side are formed asymmetrical separately. With this setup, magnetic resistance in magnetic flux passing through both inner and outer circumferential sides is uniformized over the whole orbit length of the charged particle beam rather than a position where the charged particle beam passes through whereby magnetic flux density in a gap between magnetic poles becomes uniformized.
